The fin lines have been marked and extended down the body tube. many instructions have you extend the lines all the way down the body tube. This is usually unnecessary, I don't want the pencil lines to show through light color of spray paint.
The fin root edge was used to mark the intersection or front of the leading edge intersection. I only extend the line a little forward of this tick mark.
To get a better grab of the glue, the alignment lines are sanded off.
If you concentrate on just sanding off the pencil lines, you won't rough up any more of the tube than is necessary. Keeping the block square on the line, you should be sanding off an area about 1/8" wide. Sand from the front tick mark all the way back to the rear of the tube.
Re-draw the lines back on the body tube.
It's easy to continue redraw using what little of the alignment line is left, forward of the tick mark.
Chris, I do not understand why you sand the line off of the tube and then state: "Re-draw the lines back on the body tube." Why re-draw them onto the tube after you sanded them off?
